	 * The LocalBusyIndicator is a special version of the
	 * BusyIndicator. This one doesn't block the whole screen - it just
	 * blocks the corresponding control and puts a local animation over the
	 * control. To use the functionality of this control the corresponding
	 * control needs to be enabled via the 'LocalBusyIndicatorSupport'
	 * accordingly to the ListBox control (see the init-function of the
	 * ListBox).
	 * @extends sap.ui.core.Control

	 * @author SAP SE
	 * @version 1.46.7
	 *
	 * @constructor
	 * @public
	 * @since 1.11.0
	 * @deprecated Since version 1.14.2.
	 * The LocalBusyIndicator Control is not needed anymore by the new implementation of the LBI. Hence, it is not used anymore.
	 * @alias sap.ui.core.LocalBusyIndicator
	 * @ui5-metamodel This control/element also will be described in the UI5 (legacy) designtime metamodel
